Leptinella Information
The brass buttons plant gets its name from the small yellow to green flowers it produces in the spring. The plant is in the daisy family, and its flowers look very much like the centers of daisy flowers, minus the long white petals. These small, hard-looking flowers are said to resemble buttons. Leptinella brass button plants are native to New Zealand but are widespread now. They are hardy from USDA zones 4 through 9, though just what that means depends on the zone. In 9 and 10, the plants are evergreen and will last all year. In colder climates, the leaves may die back. If protected by snow or mulch, the leaves will turn brown but stay in place. If exposed to the cold winter air, the leaves will die and new ones will grow in the spring. This is fine, though the new leaf growth will take a month or two to come back and the plant won’t be as attractive in the spring.
Growing Brass Buttons
Growing brass buttons in the garden is very easy. In cooler climates, the plants like full sun, but in hotter areas, they fare better with partial light shade. They will grow in a wide range of soils, though they prefer well-drained, rich soil with frequent watering. They spread aggressively through runners just underground. You may need to dig them up and separate them every now and again in order to keep them in check. While some varieties boast green leaves, one particular variety that is very popular is called Platt’s Black, named for the garden of Jane Platt in which the plant was first documented. This variety has dark, almost black leaves with green tips and very dark flowers. Growing black brass buttons in the garden is a matter of personal taste – some gardeners think it looks on the verge of death, while others think it looks fascinating, especially interspersed with a bright green variety. Either way, the plant makes an exceptional specimen in the garden.
